IMPROVEMENT IN CRUSHING-PRESSES.

Spccification forming part 0!? Letters Patent No. 40,325, dated October20. 1863.

required; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 is a. side sectional view of myinn vention, taken the line :10av, Fig. 2 Fig.2, a plan or top view of the same; Fig. 3, a front or endview of the lower partof the same; Fig. 4, a detachedside view of one ofthe adjustable ways pertaining to the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to anew and improved press for crushing orpulverizing substances, and also forgiving a rollingpressure such, forinstance, as is required in expressing moisture from articles orsubstances, and in giving impressions by means of dies, types, &c.

The object of the invention is to obtain a press for theabove purposes,which will be very ett'ective or have great power and still be capableof being operated with the greatest facility or by a triflingexpenditure of power, and also be capable of being graduated so that thecrushing-power may be varied or graduated as circumstances may require.

To this end the invention consists in the employment or use of acylindrical or semicylindrical head or block provided with adjustable orsliding weights, and also provided with semicircular bearings havingstops attached and working on adjustable ways secared to a bed, allbeing arranged insuch a manner as to effect the desired end.-

To enable those skilled in the art to fully understand and-construct myinvention, I will proceed to describe it.

A represents a head or block, which may be of cylindrical orsemi-cylindrical form, the latter shape being preferable. This head orblock may be constructed of wood or metal. If the former material beused, itmay be constructed hollow or in shell form, and filled with anysuitable material, B, to give it a reguisite degree of weight. -lf thehead or block be of metal, it will probably possess sufticient weightwithout being filled, although, it'notsolid, itmay be filled. The bottomof the head or block is the round or curved part, and attach side of theheader block there is an upright arm, a, on which a-sliding oradjustablc weight, 0, is fitted. These weights may be retained byfriction only on the arnis a, or any suitable catch or fastening may beemployed to hold themat any desired point on the arms.

To each side of the lower part of the head or block A there is attacheda semicircular bearing, D. The ends of these hearings are extendedoutward a little, as shown atb b, Fig. 1, so as to raise thehead orblock as it isrolled overat either end.

E represents a horizontal bed, which has a way orguide, F, attached toeach side ot' it. These ways or'guidcs areeachformed of two longitudinalparts, 0 c, placed one over the other, and having their contiguoussurfaces inclined, as shown clearly in Fig. 4. Each of the parts a c hasan oblong slot, (7, made longitudinall y in it, and through the slots ascrew, e, passes into the bed E. These screws e hold the two parts 0 cof the ways in proper position, and also hold the ways to the bed. Thebearings. D D rest on the ways F, the rounded part otv the head or blockprojecting down a trifle'between the ways, as shown clearly iu'Fig. 3.To each bearing D, near each end, there is attached a button, G, ofcircular 'form, a segment being removed or cut off from each, so as .toleave a plane surface,

f. These buttons are attached to the sides of tho bearin gs D by screws9, which pass eccentrically through them, as shown by the dotted 'linesin Fig. 1

The operation is as follows: Suppose, for instance, an article, orsubstance is to be crushed.- It is placed on the bed E, and the.

power, the bearings and ways keeping the head or block in properposition on the bed.

The substance or article on the bed E'is crushed by the action of thehead or block,

I e g" g and the substance may be reduced .to a greater or less degreeof fineness by adj ustin'g the two parts 0 c of the ways E-that'is tosay, by drawing them longitudinally outward or inward, (see Fig. 4).-bywhich means the head or block may be adjusted at a greater or lessdistance above the surface of the bed E. At the termination of eachmovement of the head or block A the latter is raiseda' trifle' in consequence of the projecting ends I) of the bearings D. This raising ofthehead or block is important in many eases, as it enables articles Havingthus described my invention, what I claim as new, and desire to secureby Letters Patent, i s- 1. The cylindrical or semi-cylindrical head orblock A, provided with the sliding or adjustable weights 0, fitted onarms a, in connection with a bed, E, all arranged substantiall y as andfor the purpose herein set forth. 2. The bearings D, attached to thesides of the head or block A, in connection with the ways F on the bedE, for the purpose specified. 3. The ways or guides E, constructed oftwo longitudinal adjustable parts, 0 c, substantially as shown, incombination with the counterpoised head or bloclnfor the purposespecified. 4. The buttons G, attached to the bearings D, and constructedsubstantially as shown, for the purpose of holding the block in. aninelined position when tilted or turned on either end, as set forth.
